See DetailsIn the global advertising and construction industries, selecting the appropriate substrate for exterior applications is a matter of balancing structural physics with chemical stability. For professional pvc co-extruded foam board manufacturers and B2B procurement managers, the debate often centers on the manufacturing process: Co-extrusion versus the Celuka method. Jiatao Industrial Co., Ltd., a leading Chinese manufacturer with an annual capacity of 25,000 tons, utilizes advanced extrusion technology and fine cooling solidification to produce high-grade boards for dozens of countries, including the US, Germany, and Japan. Understanding the mechanical nuances between these two materials is essential for ensuring the longevity of outdoor signage, furniture, and building decorations.
The primary difference between these two materials lies in the cooling and solidification process during extrusion. A high density pvc co-extruded sheet is manufactured by simultaneously extruding a foam core and two solid, rigid PVC outer layers, resulting in a "sandwich" structure with an exceptionally smooth and hard surface. In contrast, the Celuka process involves cooling the outer surface of the board more rapidly than the core, which creates a solid skin but with a more integrated, singular material transition. While Celuka boards offer good impact resistance, the co-extruded variant typically provides a superior surface hardness that resists mechanical scratches and chemical pollutants more effectively.
| Technical Property | PVC Co-extruded Foam Board | Celuka PVC Foam Board |
| Surface Structure | Triple-layer "sandwich" (Solid-Foam-Solid) | Integrated solid skin with foam core |
| Surface Hardness (Shore D) | Higher (Designed for high-impact signage) | Standard industrial hardness |
| Scratch Resistance | Superior due to the solid PVC outer skin | Good, but more prone to deep gouging |
Outdoor signage is constantly subjected to ultraviolet (UV) radiation and thermal expansion cycles. A uv resistant pvc foam board for signs manufactured via co-extrusion allows for the concentrated application of UV stabilizers in the thin outer solid layers rather than dispersing them throughout the entire core. This targeted engineering significantly slows down the yellowing and "chalking" process compared to standard foam boards. While Celuka boards are highly durable in many interior settings, co-extruded sheets exhibit better dimensional stability in extreme temperature fluctuations, preventing the warping often seen in lower-grade waterproof pvc co-extruded board for cabinetry and exterior cladding.
For B2B wholesalers, the "workability" of the board is a critical metric. When comparing the two, the industrial grade pvc co-extruded sheet provides a more stable substrate for high-resolution UV printing and vinyl lamination. The surface of a co-extruded board is naturally glossier and flatter than Celuka, which can sometimes exhibit slight surface waves due to the rapid cooling process. Furthermore, the structural rigidity of pvc co-extruded foam board allows for larger-scale signage without the need for heavy internal framing, reducing overall project costs.
| Fabrication Metric | PVC Co-extruded Performance | Celuka Performance |
| Print Adhesion | Excellent for UV direct-to-substrate | Good, but may require surface priming |
| Screw Holding Power | Superior (Screw bites into solid outer layer) | Excellent (Consistent density transition) |
| Structural Weight | Optimal strength-to-weight ratio | Slightly heavier for equivalent rigidity |
As a large-scale professional production base, Jiatao Industrial focuses on development and production to ensure the possible service for our customers. Whether it is pvc co-extruded foam board for advertising or waterproof pvc co-extruded board for cabinetry, our products are engineered to thrive in the world's most demanding climates. Our cooperation with more than 10 of the world's top 500 enterprises is a testament to our commitment to high-grade markets. By using advanced extrusion and fine cooling solidification, we produce a diversified range of casting that meets the interior and exterior needs of the transportation, furniture, and decoration industries.
For high-load and high-impact applications, understanding the flexural and surface properties is paramount. Jiatao Industrial utilizes fine cooling solidification to ensure our high density pvc co-extruded sheet maintains superior rigidity. The triple-layer structure of the co-extruded board provides a distinct advantage in bending resistance compared to the integrated skin of Celuka boards.
Surface integrity is the first line of defense for outdoor signage. The solid PVC skin of the industrial grade pvc co-extruded sheet is significantly harder than Celuka skins, providing better protection against environmental debris and vandalism. This makes it an ideal uv resistant pvc foam board for signs in high-traffic public areas.
| Technical Metric | Testing Method | PVC Co-extruded (Jiatao) | Celuka Foam Board |
| Shore D Hardness | ASTM D2240 | 55 - 65 | 45 - 52 |
| Scratch Resistance | Wolf-Wilburn (Pencil) | 3H - 4H | H - 2H |
| Surface Finish | Visual/Gloss Meter | High Gloss / Ultra-Flat | Satin / Slight Texture |
Signage and cabinetry must resist "bowing" under their own weight or wind loads. The pvc co-extruded foam board utilizes its rigid outer layers to act as an I-beam, providing a higher flexural modulus than the more uniform density distribution of Celuka boards.
Exposure to cleaning agents and temperature swings can cause inferior boards to degrade. Our pvc co-extruded foam board is engineered with a core-to-skin adhesion that prevents delamination even under extreme chemical stress, a critical factor for the world's top 500 enterprises we supply.
| Property | Standard / Method | PVC Co-extruded | Celuka Board |
| Vicat Softening Temp. | ASTM D1525 | ≥ 75°C | ≥ 72°C |
| Chemical Resistance | ISO 175 (Acids/Alkalis) | Excellent (Solid Skin Barrier) | Good |
| Water Absorption | ASTM D570 (24hr) | ≤ 0.1% | ≤ 0.5% |
With an annual production of over 25,000 tons, Jiatao Industrial ensures that every industrial grade pvc co-extruded sheet meets international benchmarks.
